The very first time a headset is plugged in, detection is unreliablebecause bias hasn't been configured yet, it's done once a mechanicalinsertion interrupt has been triggered, so following insertions (andthus detections) are not affected.

To fix the very first detection, the bias must also be configured in thefunction that setup the MBHC. Move pm8916_wcd_setup_mbhc afterpm8916_mbhc_configure_bias to avoid a forward declaration.
